If that worked every major racing team would have a billion spark plugs run to redline and pull them, but we all know this isnt the case. Could you imagine the money companies would save by tuning by sparkplugs. If there was a reliable effective way to tune a car without investing in expensive equipment everyone would be on it. I can't tell you why those guys told you they tune that way, you should ask them. |
Could tuning by looking at plugs tell you this:

My dad used to tune by reading spark plugs....
on his 1950's vintage porsche. |

I can't comment whether or not this is true, but if it is we are in sorry shape. And this might be why people have flown in tuners from the US. Me I'll tune my own car. I'm not sure what you are after Dean. You are arguing that it's a valid method of tuning, but you are only basing this on what the "top tuners" in the city have told you. If you beleive them why are you asking here? Give ole Corky Bell a call and ask him what he thinks. He's well respected and certainly old school. |
Miata's don't make the best drag car....even still a 10sec Talon will need 30+ pounds of boost. If we could easily run 30lbs. we would.

I wonder how many motors some of these tuners have destroyed on their quest for 1/4 times? We are in sorry shape because people are telling you the better way to tune is via spark plug inspection. I want to know if the plug can tell me if I'm running 14:1 AFR or 12:1 AFR accurately. That's could be the difference between a good tune and boom. How about EGT? Knock? Jay |
